2 Claims.

This invention relates to tobacco pipes and has particular reference to novel improvements in the stem construction thereof, whereby nicotine juices incident to smoking will be trapped, thus assuring a cool, sweet smoke.

A further object is to produce a device wherein the smoke coming from the pipe will pass through a longer passage, one which is exposed and therefore one which will cool, to some degree, the smoke entering the mouth.

A still further object is to produce a device which is economical to manufacture, one which neat in appearance, and one which will not add an appreciable weight to the pipe.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawing forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

l is a side elevation ofour device,

Fig. 2 is a top plan view of Fig. 1,

Fig. 3 is a vertical cross section on the line 3-3 of Fig. 2,

Fig. 4 illustrates the manner in which our device will be applied to a pipe of different design than that shown in Figs. 1 and 2, and

Fig. 5 is an enlarged detail cross sectional view of the smoke trap.

In the smoking of a pipe, saliva often runs down the pipe and into the bowl where the tobacco is held. lhis causes a soggy condition of the tobacco and also a greater nicotine discharge, for the reason that the fire in the bowl produces a steam which accelerates the amount of juice given off by the tobacco. A certain portion of this juice is caused by condensation from the burning tobacco. Therefore, we have devised a pipe which will prevent the saliva from running into the pipe and will also prevent the juices leaving the tobacco entering the mouth, it being understood that the amount of juice condensing from the smoke will be materially reduced as no saliva reaches the tobacco.

In the accompanying drawing wherein for the purpose of illustration is shown a preferred emhodiment or" our invention, the numeral 5 desighates the usual pipe bowl having a shank 6, which is bored as at 7 to receive the customary stem 8. The stem 8 has a recess formed therein, the sides and ends of which recess are slightly tapered. This end taper is shown at Q and 11 so as to receive and tightly seal within the recess, a removable trap member 12, which also has tapering sides and ends as best illustrated in the exaggerated view of Fig. 5. A passage 13 is formed within. the trap member 12 and is so arranged that the ends of this passage will communicate with the bore 14 of the stem 8. It will be noted that the passage 13 has an incline A toward the bowl 5, and has a curved portion B toward the mouth end of the stem, this curved portion bending toward the bowl.

As disclosed to advantage in Figs. 1 and 2, it will be noted that we have provided on each side of the trap member 12, recesses 15 that serve as finger holds when it is desired to remove the trap member for cleaning purposes.

The reason for this construction is the following: Any saliva from the mouth will not pass down the bore 14 for the reason that it will first encounter the upwardly curved portion B or" the core 13 and even after the pipe is taken out of the mouth and held so that the bowl or the pipe is practically horizontal, this curved portion B will still act as a gravity check for the small amount of moistureexuded from the mouth. Any products of combustion will be trapped in the bore 1 and will, likewise, not reach the mouth.

It will thus be seen that we have produced a device which will accomplish all the objects above set forth.

It is to he understood that the form of our invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material, size, shape and arrangement of parts may be resorted to without departing from the spirit or" the invention or the scope of the subjoined claims.

Having thus described our claim:

1. In combination with the bowl and stem of a smokers pipe, of a substantially triangularshaped nicotine trap member removably secured to the pipe stem, and provided with eX- posed finger depressions to facilitate removing said trap from the stem.

2. In a trap device of the class described, adapted to be inserted into the stem of a smoking pipe, said trap device embodying a bore communicating with the stem bore and said trap bore extending upwardly and angularly from the stem bore, thence curved downwardly and inwardly and then outwardly and communicating with the mouth piece bore whereby a nicotine trap is formed in the angular section of the bore and a saliva trap is formed in the curved section thereof adjacent the mouth piece of the pipe.
